Selon les r\u00e9sultats, un ordinateur quantique pourrait d\u00e9chiffrer les cl\u00e9s priv\u00e9es Bitcoin en neuf minutes environ.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Le temps de blocage moyen de Bitcoin est de dix minutes. Cette marge tr\u00e8s mince est ce qui inqui\u00e8te les chercheurs en s\u00e9curit\u00e9.<\/span><\/p>\n<p><span style=\"font-weight: 400\">L\u2019inqui\u00e9tude n\u2019est pas seulement th\u00e9orique. Si un acteur malveillant acc\u00e8de \u00e0 une machine quantique suffisamment performante, il pourrait potentiellement voler des fonds avant m\u00eame que le r\u00e9seau ne traite un bloc.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Cela met en danger les portefeuilles d\u00e9tenus depuis longtemps, en particulier ceux qui sont inactifs.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">La recherche a contraint l\u2019industrie \u00e0 se confronter \u00e0 une question qu\u2019elle avait longtemps consid\u00e9r\u00e9e comme lointaine : que se passe-t-il lorsque la puissance quantique d\u00e9passe les normes de chiffrement actuelles ?<\/span><\/p>\n<h2><b>CZ d\u00e9crit la voie \u00e0 suivre pour la cryptographie<\/b><\/h2>\n<p><span style=\"font-weight: 400\">CZ pense que la r\u00e9ponse r\u00e9side dans la cryptographie post-quantique. Il a soulign\u00e9 que la transition vers des algorithmes r\u00e9sistants aux quantiques est tout \u00e0 fait r\u00e9alisable.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Le plus grand obstacle, a-t-il soulign\u00e9, est la coordination.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Les r\u00e9seaux d\u00e9centralis\u00e9s rendent les mises \u00e0 niveau difficiles \u00e0 organiser. Les d\u00e9bats sur les algorithmes \u00e0 adopter pourraient d\u00e9clencher des divisions et des bifurcations au sein de la communaut\u00e9 en cours de route.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Il a \u00e9galement averti que le nouveau code d\u00e9ploy\u00e9 lors de toute transition pourrait introduire de nouveaux bugs ou vuln\u00e9rabilit\u00e9s de s\u00e9curit\u00e9.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Les utilisateurs qui conservent eux-m\u00eames leurs actifs devront migrer manuellement leurs fonds vers des portefeuilles mis \u00e0 jour. Cela ajoute une autre couche de complexit\u00e9 pour les d\u00e9tenteurs de crypto quotidiens. Aucune de ces raisons ne justifie de paniquer, a soutenu CZ, mais ce sont des raisons de planifier soigneusement et d\u2019agir de mani\u00e8re d\u00e9cisive.<\/span><\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">J&rsquo;ai vu certaines personnes paniquer ou poser des questions sur l&rsquo;impact de l&rsquo;informatique quantique sur la cryptographie.<br \/>\u00c0 un niveau \u00e9lev\u00e9, tout ce que la cryptographie a \u00e0 faire est de passer \u00e0 des algorithmes r\u00e9sistants aux quantiques (post-quantiques).
